[PATCH v3 0/2] Qualcomm's lpass device tree changes for I2s dai

[Srinivasa Rao Mandadapu]

These patches are device tree changes to support audio over I2S.

Changes Since v1:
  -- Ajith's Certification is added.
  -- Alias name added for sound dai link node
Changes Since v2:
  -- sound node variable is added in sc7180-trogdor-coachz.dtsi.
  -- Audio-jack property is removed, as it may create conflicts with the boards 
     having different codecs.
